T 0 all whom it may concern:

Be it known that I, EMERY PRIME AUGER, a citizen of the United States, and a resi dent of Corinth, in the county of Alcorn and State of Mississippi, have made certain new and useful Improvements in Concrete- Block Machines, of which the following is a specification.

My invention is an improved machine for making blocks of concrete for use in buildings of various kinds, employing concrete material, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is device in which the block may be molded and then by the use of a cam lever, the sides of the mold can be loosened and let down vertically, leaving the molded block upon the base or table from which it can be readily removed.

- A further object of my invention is to provide means by which the sides of the mold may be moved simultaneously, so that there will be no danger of binding the latter against the table.

A further object of my invention is to provide a device in which the depth of the mold can be quickly and accurately changed to suit the various requirements so as to produce blocks of varying thicknesses.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view showing the device in position to receive the concrete filling. Fig. 2 is a plan view of an end portion of the device showing the mold in its locked position. Fig. 3 is a similar view showing the mold in its unlocked position. Fig. 4 is a side view of the device in its lower position, and Fig. 5 is a transverse sectional view at right angles to Fig. 4.

Referring now to the drawings, a rectangular base is provided consisting of the end members 1 and the side members 2. EX- tending upwardly at the four corners of the frame are the uprights 3. Parallel with the side members 2 are'the braces 4. The latter are secured to the corner members 3 and project beyond said members at one end of the frame to form a support for the bearingboard 5. A similar bearing-board 6 is supported by the opposite ends of the strips 4 as is clearly shown in Figs. 1 and 4. A transverse brace 7 is located centrally of the mato provide a chine and is carried by the side members 4. The frame thus far described constitutes the base of a table, which is provided with a top 8 and has downwardly extending side and end pieces 9 and 10, respectively, which serve as guides for the sides of the mold as will be hereinafter explained.

The mold itself consists of a rectangular box-like structure having the side pieces 11 and the end pieces 12. Both the side pieces and the end pieces are provided with outwardly projecting shelf portions 18 and 14, respectively, protected by the upwardly eX- tending rims 15 and 16.

The side portions of the mold are movable relatively to the end ortions of the same, so that they may be a usted to and from the latter. The means by which this is accomplished is clearly shown in Figs. 2 and 3. It consists in the provision of the rods 17 and 18 secured to the sides 11 at 19, and having curved ends pivotally secured at 20 and 21 respectively, to a clamping lever 22. Fig. 2 shows the sides in their locked position. In this position the lever 22 is thrown over to Ward the left, thereby bringing the pivotal connections 20 and 21 of the rods 18 and 17 in line, thereby drawing the ends against the sides and locking the latter. In Fig. 3 the lever is shown pulled outwardly, thereby pushing the rods 17 and 18 outwardly and forcing the sides 11 away from the ends.

The means for lowering and raising the mold frame consists of a series of actuating levers. Referring now particularly to Fig. 1, it will be seen that on the bearing pieces 5 and 6 are journaled the two bent levers 23 and 24 respectively, the journals for the latter consisting of strips of metal fastened to the bearing-boards and bent around to provide a suitable bearing for the rods. The levers 23 and 24 are bent at a right angle at 25 and the shorter arms of the levers are bent laterally to pass through the bearings at each end of the bearing supports 5 and 6 and on the other side of the machine are bent at right angles again to form arms similar to the short arms. The bent portions are attached to swinging links 26 by means of a pivot 27. The links 26 are pivotally attached to one of the side members 11 in the same manner as the links 27 are attached to the side members 11 on the o posite side.

The links 27 are pivotally attached to the levers 23 and 24 at 28 and 29, respectively.

. the longitudinal member .4.

a cross bar 30 extends between the two levers 23 and 24 and is pivotally secured thereto so that both levers may have simultaneous movements. The upper ends of the levers 23 and 24 are bent to form handles 31. V

In order to provide a support for the movable sides of the mold in t ieir shifted positions, I have arranged the rods 32 and 33 on either side of the frame. reality made of upright arms of a U-shaped rod, whose connecting member 34 isjournaled on the side of the base members 2, as clearly shown in Figs. Upon the rods 32, 33 are arranged 1 and 5. theclamping lugs 35. These lugs are movable relatively of the rods and may be secured in any positionby means of the set screws 36. The rods 32 and-33 may beshifted toward and from the frame to bring the stops 35 into linewith the movable mold so thatthe latter can rest uponthe stops. In

order to shift the rods I have provided the treadle 37, which is pivoted at 38 in a slot in I n The opposite end of the treadle lever is connected by a link 39 to a pair ofpivoted arms40 and 41 at their pivotal connection. The arms 40 and 4,1 are secured to the rods 34 oneither side of the arms 40 and 41 link .39, thereby shifting the uprights 32 and 33, together with theirstops 35, out .ofthe' way of the movable mold, thereby permit ting it to be lowered intothe position shown in Fig 5. On the release of the treadle 3? the arms 41 and 40 are put under spring tension by means of the spring 42, which isse.

cured to the cross brace 7,. Itwill be seen therefore that when the mold again lifted, the upper stops 35 will at once spring underneath the moldand su port it. a Having thus descri ed the various parts of the device, the operation will be easily understood. In practice the device is raised by means of the levers 23 and 24 in the posi-. tion shown in Fig. 1. In. this figure dividing pieces 43 are shown in position for molding window sills. With the molds in position,

, the charge of wetconcreteis put in and packeddown in the customary manner, the clamping lever 22 beingturned so as to bring the sides and ends closcly together. After the material in the molds has beenfsubjected to suflicient pressure, the clamps 2" are. drawn outwardly into the positionshown in Fig. 3, thereby loosening the sides of the mold and permitting it to be easily lowered intothe position shown in Fig. 4-, This is accomplished by means of the levers23 and 24. The handles 3]. are grasped and they are swung from right to left i An inspection of the drawings will show that the movement of. the handlesin this directionwill cause the mold to descend, the links 26 and 27 on either These rods are in i one piece and constitute the side of the mold moving uniformly downward and allowing themold to descend without tilting. In order to permit the descent of the mold the treadle 37 is pressed in the manner already described, thereby throwing the upper stops 35 out of engagement with the mold and allowing it to assume the position shown in Fig. 5. As the mold descends, the concrete blocks, together with the dividing members 43, are left in position upon the top of the table, the latter of course forming the bottom of the mold. From thence the blocks. can be easily transported to the lacein which they are to be set to thoroughly arden.

Obviously other forms of mold than that shown herein could be used with my im proved concrete block machine.

The main object of my inventiomas has been stated before,.is to provide a machine in which the sides of the mold may be drawn; downwardly away from the molded material leaving the latter in'a perfectly molded condition and free from the outside mold upon the table.
